Comment (by isasi):
The video has edit list which makes it discard the last frame
elst:
segment_duration, media_time
90090, 0
90090 when converted to stream timescale becomes 60060 . The last sample
starts with the timestamp of 60060 . If played through Quicktime 10.4 we
can see that the player only plays till last but one frame. If we export
the video using Quicktime we only get 59 frames. So ideally we should get
59 frames.
If we do ffprobe -show_frames we do, actually get 59 frames. But somehow
while converting to png one frame is discarded.
